- The 'Wow!' signal, detected in 1977, remains unexplained and is considered a strong candidate for extraterrestrial origin.
- Recent studies using modern techniques found the signal was more intense than previously thought, at 250 Janskys.
- The signal is unlikely to be from terrestrial interference, satellites, or comets, based on statistical analysis.
- Researchers propose the signal might originate from cold hydrogen clouds in the interstellar medium, possibly triggered by a cosmic event like a magnetar flare.
- The study does not confirm extraterrestrial origin but refines future searches for technosignatures and biosignatures.
- The 'Wow!' signal has never been detected again, and the mystery remains open for further investigation.
